Embodiment 1

[0041] The method for planting beads of reflective material glass beads comprises the following steps:

[0042] a. Place the glass beads 8 in the trough 6, and heat the heating roller 3 to 50°C;

[0043] b. PET composite film 7 is heated by heating roller 3;

[0044] c. The glass beads 8 in the material trough 6 are evenly spread to the viscous film surface of the heated PET composite film 7 by the feeding roller 5, so as to obtain a PET composite film with evenly distributed glass beads.

[0045] Preferably, the adhesive film layer of the PET composite film 7 is a hot-melt resin film layer. Such as: polyester resin, elastic polyurethane resin, polyvinyl alcohol resin.

Embodiment 2

[0047] In the bead planting method of reflective material glass beads, in step a, the heating roller 3 is heated to 80° C., and preferably, the adhesive film layer of the PET composite film 7 is a thermoplastic resin film layer. Such as: polyethylene vinyl acetate resin, polyethylene resin.

[0048] All the other implementation steps and modes are the same as in Example 1.

Embodiment 3

[0050] In the bead planting method of reflective material glass beads, in step a, the heating roller 3 is heated to 160° C., and preferably, the adhesive film layer of the PET composite film 7 is a thermoplastic resin film layer. Such as: polyethylene vinyl acetate resin, polyethylene resin.

[0051] All the other implementation steps and modes are the same as in Example 1.

Abstract

Aiming at the defects in the prior art that the amount of planted glass beads is not easily controlled, the planted beads are not uniform, the process is complex and the like, the invention discloses a bead planting method of glass beads of reflective materials. The method comprises the following steps: a) putting the glass beads into a trough, and raising the temperature of a heating roller to 50-180 DEG C; b) heating a PET (Polyethylene Terephthalate) composite membrane through the heating roller; and c) uniformly scattering the glass beads in the trough through a feeding roller onto the surface of a sticky film layer of the heated PET composite membrane to obtain a PET composite membrane with uniformly-distributed glass beads. The method is simple in process and easy in operation. The temperature of the heating roller is set so that the glass beads can be more firmly stuck on the surface of the sticky film layer of the PET composite membrane. The glass beads on a planted-bead surface are tightly and uniformly arranged, the distribution density of the glass beads in a unit area can be regulated as required, and the use ratio of raw materials is increased.

Description

technical field [0001] The invention relates to a method for planting beads of reflective materials, in particular to a method for planting beads of glass beads of reflective materials. Background technique [0002] Reflective materials can be divided into two categories: glass bead type and micro prism according to their different retroreflection principles. In the production of glass bead-type reflective materials, the bead planting link has a significant impact on the optical performance of the product. The traditional process often uses the bead planting surface of the substrate to directly contact the static glass beads, so that the bead planting surface of the substrate During the process of the adhesive running with the substrate, the method of naturally adhering to the glass beads will easily cause uneven distribution of the glass beads and cannot be arranged closely. The glass beads overlap layer by layer, which seriously wastes raw materials and affects the reflect...
